Transposition of the Great Arteries (TGA) Clinical Pathway — CICU

Immediate Post-operative CICU Care

  Goals Recommendations
Hemodynamics Vital Signs
  • HR < 160
  • SBP > 60
  • DBP > 30
  • MAP > 40
  • Urine output ≥ 0.5 mL/kg/hr
  • Begin furosemide IV POD1
  • pH 7.35-7.45, minimal base deficit
  • Normothermia 36-37.5°C
  • Titrate infusions:
    • Dopamine: 3-5 mcg/kg/min
    • Milrinone: 0.3-0.5 mcg/kg/min
    • Epinephrine: 0.01- 0.05 mcg/kg/min
  • Discontinue for adverse effect or when no longer needed
  • IV fluids at maintenance rate
  • If cardiac output inadequate, obtain echocardiogram and ECG
  • Low-grade fever within first 24 hrs is common after bypass. For fever outside this window, refer to CICU Fever Guidelines
Respiratory
  • Normal work of breathing
  • pH 7.35-7.45
  • CO2 < 45
  • Consider extubation when:
    • PEEP 3-6
    • Rate 5-10
    • Pressure support 5-10
  • Maintain SpO2 > 92%
  • Initial vent settings discussed at handoff
  • Potential barriers to extubation include
    • Bleeding
    • Hemodynamic instability (low cardiac output, arrhythmias)
    • Decreased level of consciousness
Neurologic
  • Video EEG
    • Within 6 hrs of CICU arrival
    • Continue for 48 hrs
If seizures detected, discuss treatment with Neurology
Diagnostic Studies
  • CXR
    • Upon CICU arrival
    • POD 1
    • After removal of thoracic lines, drains
  • ABG
    • Upon CICU arrival
    • Q1hr x 2
    • Q2hr x 2
    • Q4hr for remainder of first 24 hrs
 
Pain Management
Nutrition Follow Clinical Pathway: Nutrition in Neonates after Surgery for CHD
Hemostasis
  • Hemostasis commonly achieved upon CICU arrival
  • Routine coagulation profile not routinely indicated
  • For ongoing bleeding:
    • Avoid hypertension
    • Obtain CBC, INR/PT/ PTT/fibrinogen
    • Maintain:
      • Hgb > 10 g/dL
      • Fibrinogen > 150
      • Platelets > 100
      • PT < 15
      • PTT < 50
    • Notify surgeon
    • Repeat labs as indicated
